BACKGROUND

Sugary foods and drinks are an important part of cultural and lifestyle habits across the world, but the sugar they contain has been linked to obesity, diabetes, poor dental health, and disruptive behavior in people. Because of this, consumer preferences have been shifting away from sugar-containing foods, and governments are increasingly implementing regulation to encourage the consumption of less sugar.

As such, industry has been searching for appropriate low-calorie sweeteners for many decades to substitute for sugar in food and beverages. Unfortunately, many sugar substitutes are produced from non-natural resources, and often offer bitter undertones or other unpleasant tastes along with their sweetness, both of which consumers find unappealing. Moreover, while many sweeteners are able to mimic the sweetness of sugar in food and drinks, few are able to mimic the broad range of roles that sugar plays in food, such as adding bulk, modulating texture, providing structure, acting as a preservative, and modulating colour and flavour through caramelisation and Maillard reactions. In addition, many bulking sweeteners that are able to mimic these physical properties of sugar have gastrointestinal tolerance issues that limit their use to levels well below the amount required to replace sugar in a standard Western diet.

Dietary fibre is an important part of a positive diet and helps maintain digestive health and a well-regulated gut flora. Such fibre comprises saccharides of varying chain lengths and types. In addition to being found naturally in a wide spectrum of foods, fibre can also be produced separately and added to other foods during their manufacture.

Compositions with Combinations of Polysaccharides and Oligosaccharides

A composition may comprise a combination of polysaccharides and oligosaccharides. The source of the polysaccharides in such compositions may contain cellulose, such as plant biomass, for example the undigested component of partially digested plant biomass, such as the undigested plant biomass from the same reaction as that which produced the oligosaccharides. The polysaccharides in the undigested biomass may comprise lignin, polyphenol, cellulose, lignocellulose, or any other suitable polysaccharides as described herein. Addition of polysaccharides to oligosaccharide mixtures can be done to improve the gastrointestinal tolerance of the oligosaccharide mixtures.

Enzymatic Reactions

One step of the method of forming or manufacturing the composition??? may be an enzymatic reaction, in which one or more enzymes are placed in a suitable reaction vessel together with one or more feedstocks, which may be soluble or insoluble in water, and a suitable solvent.

A variety of enzymes may be suitable for use in the enzymatic reaction. Any enzyme which produces oligosaccharides when acting on a polysaccharide-containing feedstock may be appropriate, and it is within the ability of the skilled person to select suitable enzymes. Preferably, the enzymatic reaction comprises a cellulase, an endo-glucanase, a cellobiohydrolase, a lytic polysaccharide monooxygenase (LPMO), a lichenase, a xyloglucan endoglucanase (XEG), a mannanase, a chitinase, and/or a xylanase.

More preferably, the enzymatic reaction comprises a cellulolytic preparation from a species, such as Trichoderma reesei, which may be purified and/or pre-treated and/or may be supplemented with one or more additional enzymes, for example, adding a beta-glucanase (SEQ ID NO: 14), a beta-xylanase (SEQ ID NO: 16) and a cellobiohydrolase, or a beta-glucanase, a beta-xylanase, an LPMO and a cellobiohydrolase, or an LPMO and a xylanase, or an LPMO, a xylanase, and a lichenase. Each enzyme may be provided to the enzymatic reaction as a purified enzyme, a semi-purified mixture derived from some natural source or lab-grown culture, in the form of a microbial strain engineered to produce the enzyme, or in any other manner. Fusions of these enzymes, either with other enzymes or with non-enzymatic modules such as carbohydrate-binding modules (CBMs), are also envisaged within each respective term, for example, an LPMO fused to a CBM, a xylanase fused to a CBM, or a xylanase fused to an LPMO.

As used herein, “cellulase” refers to an enzyme that has, or a group of enzymes that collectively have, hydrolytic activity against cellulose, for example, an enzyme preparation containing endo-1,4-beta-glucanase, cellobiohydrolase, and/or beta-glucosidase activities. Such enzymes may be able to cleave glycosidic bonds in one or more forms of cellulose, including cellulose found in plant biomass. In doing so, they can produce products including glucose and cello-oligosaccharides.

As used herein, “cellobiohydrolase” refers to an enzyme that has hydrolytic activity against cellulose and produces mainly cellobiose as a product. Cellobiose is a disaccharide and is a cello-oligosaccharide. Such enzymes are able to cleave glycosidic bonds in one or more forms of cellulose, including cellulose found in plant biomass. Preferable cellobiohydrolases are from the GH6 and GH7 enzyme families, such as cellobiohydrolase 12 and 13 from Aspergillus niger (SEQ ID NO:20 and 21) more preferably, Cel6A or Cel7A enzymes derived from Trichoderma reesei (SEQ ID NOs:10 and 11).

As used herein, “beta-glucosidase” refers to an enzyme that has hydrolytic activity against cellulose and produces mainly glucose as a product. Such enzymes are able to cleave glycosidic bonds in one or more forms of cellulose, including cellulose found in plant biomass. Preferred beta-glucosidases include GH3 beta-glucosidases from Trichoderma reesei (SEQ ID NO:22).

As used herein, “lytic polysaccharide monooxygenase” and “LPMO” refer to a class of enzymes able to oxidatively cleave polysaccharides using a copper comprising moiety and using an oxygen source, such as a molecule of dioxygen, peroxide, or any other oxygen source; and a suitable reducing agent. As such, when an LPMO is used, the enzymatic reaction may be carried out under aerobic conditions. Suitable reducing agents are not particularly limited, but examples include ascorbic acid, gallic acid, cysteine, NADH, NADPH, pyrogallol, dithiothreitol, cyanoborohydrides, borohydrides, photosynthetic pigments, lignin, lignols, and a combination of cellobiose and cellobiose dehydrogenase. While the skilled person knows a wide variety of photosynthetic pigments which may be used, thylakoids and purified fractions, or chlorophyllin, are preferred, and light may be supplied. Preferably, LPMOs are selected from the following families: AA9, AA10, AA11, AA13, AA14, and AA15. More preferably, the LPMO is PaLPMO9E (SEQ ID NO:1), an AA9 LPMO originally isolated from the ascomycete fungus Podospora anserina. More preferably still, the LPMO is an AA9 LPMO from Trichoderma reesei (SEQ ID NO:25).

Aerobic conditions may comprise the addition of oxygen, which may be provided by aeration of the substrate mixture with an oxygen-comprising gas, such as air. Aeration may be conducted by the introduction of oxygen-comprising air bubbles into the aqueous substrate mixtures by various systems, such as an air-injector, an aeration frit, a membrane system, or an internal-loop airlift reactor. Preferably, the concentration of molecular oxygen in the enzymatic reaction is from about 4 mg/L to about 14 mg/L.

Another exemplary enzyme is a lichenase, which may be selected from the GH5, GH7, GH8, GH9, GH12, GH16, GH17, or GH26 families, preferably a GH16 enzyme, more preferably a GH16 enzyme derived from Bacillus subtilis (SEQ ID NO:2). The enzyme may be able to act on, for example, mixed-linkage glucans, which are glucans comprising a mixture of β-1,3 and β-1,4 linkages, and may cleave them at β-1,4 glycosidic bonds. In the preferable case in which the lichenase acts on a mixed-linkage glucan, the β-glucans produced may fall largely within the size range of from 3 to about 7 residues, so they are particularly useful in the food, cosmetics, and nutraceutical industries. Mixed-linkage glucans are abundant in members of the grass and horsetail families, and as such, grass-based feedstocks such as straw have high levels of mixed-linkage glucans and may be acted upon usefully with lichenases. Preferred lichenases include GH5 lichenase from Bacillus subtilis (SEQ ID NO:2).

Another alternative enzyme is a xylanase, which may act on, for example, feedstocks comprising a xylan backbone. The xylanase may be, for example, a glucuronoxylanase, an arabinoxylanase, or a glucuronoarabinoxylanase. The enzyme may be active on a variety of polymers having a xylan backbone, such as glucuronoxylan, arabinoxylan, and glucuronoarabinoxylan. These polymers are abundant in various plant-derived feedstocks, for example, both hardwood and softwood may comprise appropriate polysaccharides, with hardwood often comprising glucuronoxylan and softwood often comprising arabinoglucuronoxylan. Preferred xylanases include GH5 xylanases from Ruminiclostridium thermocellum (SEQ ID NO:3) and Gonapodya prolifera (SEQ ID NO:4), and GH30 xylanases from Dickeya chrysanthemi (SEQ ID NO:5), Bacillus subtilis (SEQ ID NO:6) and Bacteroides ovatus (SEQ ID NO:7) and Trichoderma reesei (SEQ ID NO:15 and 16).

Another alternative enzyme is a mannanase, which may act on, for example, feedstocks comprising a mannan backbone. The mannanase may be, for example, a mannanase, an glucomannanase, a galactomannanase or a galactoglucomannanase. The enzyme may be active on a variety of polymers having a mannan backbone, such as mannan, glucomannan, galactomannan or galactoglucomannan. These polymers are abundant in various plant-derived feedstocks, for example both hardwood and softwood may comprise appropriate polysaccharides. Preferred mannanases include GH5 mannanases from Trichoderma reesei (SEQ ID NO:17) and Aspergillus niger (SEQ ID NO:19) and a GH26 mannanase from Aspergillus niger (SEQ ID NO:18).

Other enzymes include xyloglucanases and xyloglucan endoglucanases (XEGs), which are produced by numerous organisms, including plant-pathogenic microbes. Xyloglucanases and XEGs may be able to act on xyloglucan, a hemicellulosic β-1,4 glucan chain abundant in the primary cell wall of higher plants, which is decorated with xylose, some of the xylose residues being further decorated with other residues, such as galactose. When appropriate xyloglucanases or XEGs act on xyloglucan, the products may comprise xyloglucan oligosaccharides having a main chain of a length useful in the foodstuff, cosmetics, and nutraceutical industries. Preferred xyloglucanases include is a GH5 xyloglucanase from Bacteroides ovatus (SEQ ID NO:8), and a GH74 xyloglucanase from Trichoderma reesei (SEQ ID NO:9).

Enzymes used in such enzymatic reactions may have a sequence which has at least 70%, 75%, 80%, 85%, 90%, 95%, or 100% identity to a sequence of SEQ ID Nos: 1-25. Enzymes used herein may be functional equivalents of enzymes described herein or functional equivalents of SEQ ID Nos: 1-25.

The enzymatic reaction may take place in solution and/or suspension or in a suitable reaction vessel. At a temperature or temperature protocol appropriate for the particular combination of enzyme and feedstock, the reaction may be allowed to progress for a certain amount of time (e.g., a predetermined amount of time), until the products have reached a desired concentration, or until some other requirement has been met.

As used herein, “suspension” refers to a composition comprising at least two immiscible phases, for example, a solid and a liquid phase, wherein the weight of the solid phase may be, as a percentage of the weight of the composition, in the range of from 0.5% to 30%, preferably from 1% to 20%, more preferably from 2% to 15%, yet more preferably from 3% to 10%. The suspension may comprise a suitable solvent, which is preferably water.

In order to ensure optimal contact between the enzymes and feedstock, the reaction mixture may be agitated, either constantly or at intervals. The agitation may take the form of (i) rhythmically moving the entire reaction vessel, (ii) a fan or other stirring device, (iii) a bubble spurging, or any other suitable method of agitation.

The enzymatic reaction may be a microbial fermentation. The temperature and reaction time may be suitable for the growth of the microbial organism used. The microbial organism may be genetically altered to produce an enzyme suitable for the production of an oligosaccharide composition. The microbe may be, for example, a bacterium, for example Escherichia coli, or a fungus, such as Saccharomyces cerevisiae or Trichoderma reesei.

In some embodiments, an expression vector suitable for modifying the subject microorganism may be used such that it produces an enzyme or mixture of enzymes as described elsewhere herein. Where desired, the expression vector, which may be a plasmid or any other nucleic acid able to induce production of the enzyme, may comprise one or more of the following regulatory sequences so as to control the expression of the exogenous enzyme: regulatory sequences of a heat shock gene, regulatory sequences of a toxicity gene, regulatory sequences of a spore formation gene, or any other suitable regulatory sequence.

The enzymatic reaction can be carried out at a temperature or temperature protocol appropriate to the enzymes and substrates used. For example, the enzymatic reaction may be carried out at a constant temperature in the range of from 10° C. to 100° C., preferably from 20° C. to 80° C., more preferably from 40° C. to 60° C. If the enzymatic reaction takes the form of a microbial fermentation the temperature may be appropriate for such, for example, the enzymatic reaction may comprise the growth of E. coli and/or the temperature may be substantially constant and about 37° C.

The pH of the solution or suspension may affect the activity of the enzymes. Control of pH may aid in assuring that an enzymatic reaction proceeds at a suitable rate. The enzymatic reaction may take place at a pH in the range of from 2 to 10, preferably 3 to 8, more preferably 4 to 6.

The enzymatic reaction may be allowed to continue for a certain time period before optionally being quenched and the products isolated or otherwise collected. This time period may be from 1 minute to 6 days, and is preferably from 0.5 days to 5 days, more preferably from 16 hours to 96 hours. The reaction may alternatively be allowed to proceed until no further catalysis occurs.

The one or more feedstocks added to the enzymatic reaction may comprise polysaccharides. Such polysaccharides may have been produced by a separate reaction proceeding simultaneously or substantially simultaneously in the reaction vessel. The polysaccharides present in the enzymatic reaction may be partially cleaved by enzymes into useful oligosaccharides, leaving partially cleaved or uncleaved polysaccharides, which may include, but are not limited to, cellulose, xylan (such as glucuronoxylan, arabinoxylan, or glucuronoarabinoxylan), mannan (such as glucomannan, galactomannan, or galactoglucomannan), mixed-linkage glucan, xyloglucan chitin, chitosan, or lignocellulose.

The enzymatic reaction may be allowed to continue to run until there is from 5% to 75% undigested polysaccharide-containing feedstocks remaining, preferably 5% to 70%, preferably 5% to 65%, more preferably 5% to 55%, or more preferably 10% to 50%. This can be monitored or checked by reducing end assays, such as the anthrone assay and/or by chromatographic methods such as thin-layer chromatography and/or high-performance anion exchange chromatography.

Any substance which comprises appropriate polysaccharides may form part of the feedstock. As the foodstuff, cosmetic, and nutraceutical industries generally use a broad variety of oligosaccharides, the polysaccharides appropriate for taking part in the enzymatic reaction are not particularly limited. Feedstocks suitable for producing the oligosaccharide profile may comprise, for example, cellulose, lignocellulose, chitin, chitosan, xylan (such as glucuronoxylan, arabinoxylan, and glucuronoarabinoxylan) and/or mannan (such as glucomannan, galactomannan, or galactoglucomannan), however, any feedstock which can be suitably acted upon is envisaged. Preferably the feedstocks comprise sugar cane, corn stover, corn cob, wheat bran, wheat straw, hardwood, or softwood.

The feedstocks comprising such polysaccharides are also not particularly limited, as most plant matter is rich in such polymers. As such, the feedstock may comprise plant biomass such as grain, grain chaff, bean pods, seed coats, and/or other seed materials; seaweeds; corn stover, straw, bagasse, miscanthus, sorghum residue, switch grass, bamboo, and/or other monocotyledonous tissue; water hyacinth, leaf tissue, roots, and/or other vegetative matter; hardwood, hardwood chips, hardwood pulp, softwood, softwood chips, softwood pulp, paper, paper pulp, cardboard, and/or other wood-based feedstocks; crab shells, squid biomass, shrimp shells, and/or other marine biomass, and/or any combination of appropriate feedstocks. Preferably, the feedstock comprises wheat straw or wood. As any given natural feedstock is likely to comprise a mixture of different polysaccharides, it will sometimes be the case that a mixture of different enzymes is beneficial. Such a mixture may comprise one or more of any other enzyme. For example, such a mixture might comprise an LPMO with an endo-glucanase, a xylanase with a lichenase, a cellobiohydrolase with a mannanase, or an endo-glucanase with a cellobiohydrolase, in which the enzyme partners are present in molar ratios preferably from 1:100 to 100:1. In addition, as many appropriate feedstocks are recalcitrant, pre-treatment of the feedstock is envisaged.

As used herein, “pre-treatment” is any process which makes a feedstock more easily acted upon by the enzymes inherent in the enzymatic reaction step. The pre-treatment can occur before the enzymatic reaction, and may comprise acid treatment by, for example, sulphuric acid, phosphoric acid, or trifluoroacetic acid; alkali treatment by, for example, potassium hydroxide, sodium hydroxide, or ammonia fibre expansion; heat treatment by, for example, hot water, hot steam, or hot acid; ionic liquid treatment, and related technologies; Alcell pulping, and related technologies; supercritical solvent, such as supercritical water treatment; and/or enzyme treatment by, for example, a hydrolase, lyase, or LPMO, or any mixture of the above processes.

After the enzymatic reaction has progressed to a desired point, the one or more oligosaccharides and the one or more polysaccharides from the enzymatic reaction mixture are separated. This process can be performed in a variety of ways depending on the composition of the biomass used and the specificity of the enzymes used. As the reaction mixture will often comprise a mixture of soluble oligosaccharides and insoluble polysaccharides, the reaction mixture may be filtered to remove insoluble matter and prepare the soluble oligosaccharide obtained for further processing.

When used herein and otherwise unqualified, “soluble,” “solubility,” and grammatical variants refer to solubility in water.

The oligosaccharides may also be separated from the polysaccharides in a number of ways. They may be isolated based on solubility, so that a composition of soluble saccharides only is extracted for further processing, and/or isolated chromatographically to produce a composition with a narrower band of oligosaccharide chain lengths. Isolation may, for example, be based on precipitation, size-exclusion chromatography, ion-exchange chromatography, or filtration, ultrafiltration, or nanofiltration. In the case that isolation based on solubility is carried out, the profile of saccharides present in the isolated composition will depend on the original enzymatic reaction, as different polysaccharides decrease in solubility with length at different rates.

Also envisaged is the further treatment of all or part of the produced oligosaccharides to produce further products before incorporation into a foodstuff, cosmetic, or nutraceutical. This further treatment may comprise any chemical, physical, or enzymatic step, such as reduction, preferably reductive amination where appropriate; oxidation, caramelisation, modification with a Schiff base, or via the Maillard reaction, or by any combination of such steps, and may provide different products having properties which are improved for the desired purpose. For example, the caramelisation properties, calorific value, flavour, and colour may be modified. The oligosaccharides may also be purified, for example, through precipitation, size-exclusion chromatography, ion-exchange chromatography, or filtration, ultrafiltration, or nanofiltration.

Also envisaged is the further treatment of all or part of the produced polysaccharide fraction to produce products with improved properties before incorporation into a foodstuff, cosmetic, or nutraceutical. This further treatment may comprise any chemical, physical, or enzymatic step, such as alkylation or acid-treatment. The polysaccharides may also be purified, for example, through precipitation, size-exclusion chromatography, ion-exchange chromatography, or filtration, ultrafiltration, or nanofiltration.

Following optional modification and/or purification of the oligosaccharide and polysaccharide fractions, all or part of the fractions are then recombined at a ratio of from 1:100 to 1:1 polysaccharide:oligosaccharide, preferably from 1:10 to 1:1, preferably from 1:90 to 1:2, preferably from 1:80 to 1:3, preferably from 1:70 to 1:4, or preferably from 1:60 to 1:5. The specific ratio may depend on the desired properties of the final ingredient as well as the modifications and purifications that have been applied to the fractions. It may not be required to recombine all of the oligosaccharide and polysaccharide isolated from the enzymatic reaction. An example of a composition that can be generated by recombination of oligosaccharides is shown in FIG. 1. As shown in FIG. 1, the composition can have one or more oligosaccharides, wherein each type of oligosaccharide may have oligosaccharides with varying degrees of polymerization.

The fractions can be recombined in a variety of ways, for example, by mixing a solution comprising all or part of the oligosaccharide fraction and a solution and/or suspension comprising all or part of the polysaccharide fraction, which may further be spray-dried, lyophilised, or condensed in some other way. The fractions may also be recombined by mixing a dry form comprising all or part of the oligosaccharide fraction produced by spray-drying, lyophilisation, or condensation in some other way, with a dry form comprising all or part of the polysaccharide fraction, produced by spray-drying, lyophilisation, or condensation in some other way.

The oligosaccharide components of the final composition may comprise one or more of any type of oligosaccharide. Preferably they comprise cello-oligosaccharides, xylo-oligosaccharides, mixed-linkage glucan oligosaccharides, manno-oligosaccharides, xyloglucan oligosaccharides or chito-oligosaccharides, or derivatives of any of the aforementioned oligosaccharides.

Any such dry or liquid composition may be deemed an ingredient suitable for incorporation into a foodstuff, cosmetic, or nutraceutical at any stage of this process. This includes compositions that may be deemed to be an intermediate during the method, such as a composition formed after the recombining of the oligosaccharide and polysaccharide fractions prior to any further purification, optimisation, drying, dissolving, or any other such steps, as well as including the final composition obtained from the method.

As described herein, dry compositions may be formed by well-known methods in the art such as spray-drying and/or lyophilisation. The dry compositions can be dissolved into a solution of various liquids including water, syrups, pastes, solvents, alcohols, etc. to form the liquid composition ingredient suitable for incorporation into a foodstuff, cosmetic, or nutraceutical. Liquid compositions may be particularly useful in foods that require a smooth texture such as candy, chocolate, and yoghurts.

Following optional modification and/or purification of the oligosaccharide and polysaccharide fractions, all or part of the fractions may then be recombined at a ratio of from 1:100 to 1:1 polysaccharide:oligosaccharide, preferably from 1:10 to 1:1, preferably from 1:90 to 1:2, preferably from 1:80 to 1:3, preferably from 1:70 to 1:4, or preferably from 1:60 to 1:5. The specific ratio may depend on the desired properties of the final ingredient as well as the modifications and purifications that have been applied to the fractions.

Once a composition of the oligosaccharide products suitable for the application being considered is obtained, and further treatment and/or isolation is optionally carried out, the derivation of a foodstuff, cosmetic, or nutraceutical from the composition can furnish a very broad array of potential uses. The ingredients as described herein, can be useful in applications in which oligosaccharides, sugar, bulking sweeteners, low-intensity sweeteners, or other related food ingredients are conventionally used.

In some embodiments, a method for producing a foodstuff, cosmetic, or nutraceutical ingredient is described. The ingredient may comprise one or more oligosaccharides and one or more polysaccharides. The method may comprise the steps of:

-   -   a) forming the one or more oligosaccharides and the one or more         polysaccharides by an enzymatic reaction, said enzymatic         reaction comprising the step of contacting, in a solution or         suspension, one or more polysaccharide-cleaving enzymes and one         or more feedstocks, wherein the one or more feedstocks comprise         sugar cane, sugar cane bagasse, corn stover, corn cob, wheat         bran, wheat straw, hardwood, softwood, cellulose, chitin,         chitosan, xylan, xyloglucan, mixed-linkage glucan, mannan or         lignocellulose;     -   b) separating the one or more oligosaccharides and the one or         more polysaccharides from the enzymatic reaction mixture; and         then     -   c) recombining the one or more oligosaccharides and the one or         more polysaccharides to form the ingredient.

In some embodiments, the ingredient comprises three or more oligosaccharides of different molecular weights, wherein the method may comprise forming the three or more oligosaccharides by an enzymatic reaction, said enzymatic reaction comprising the step of contacting, in a solution or suspension, one or more polysaccharide-cleaving enzymes and one or more feedstocks.

The polysaccharide-containing feedstock may be pre-treated by acid, alkali, heat, pressure, and/or enzyme treatment. The polysaccharide-cleaving enzyme(s) may be operably linked to a catalytic or non-catalytic module, preferably wherein the polysaccharide-cleaving enzyme is operably linked to a non-catalytic module and the non-catalytic module is a carbohydrate-binding module.

The oligosaccharides may be purified; and/or undergo chemical, physical, or enzymatic treatment, such as reduction, oxidation, caramelisation, or Maillard reaction; and/or are recombined by combining a spray-dried powder of oligosaccharides with a dried polysaccharide powder.

EXAMPLES Example 1—Improved Dissolution of a Cello-Oligosaccharide and Xylo-Oligosaccharide Combination Composition

Combining cellobiose with xylo-oligosaccharide improves the dissolution of xylo-oligosaccharides in jam.

1. 280 g strawberries were brought to boil in a saucepan.

2. After heating, the strawberries were blended.

3. 5 g of xylo-oligosaccharides in powder form, or 10 g of a 50:50 mix of xylo-oligosaccharides and cellobiose in powder form, was added to the blend.

4. After being left for 1 minute the powder was mixed in to the jam.

5. The xylo-oligosaccharide sample formed a clump that was difficult to mix into the blended strawberries, whereas the xylo-oligosaccharides and cellobiose mixture readily dispersed into the jam and did not form any clumps.

Example 2—Improved Dissolution of Oligosaccharide Combinations in Water

Dissolution of xylo-oligosaccharides into water are improved when mixed with other oligosaccharides such as cello-oligosaccharide, manno-oligosaccharide, and mixed-linkage glucan oligosaccharides (MLGOs).

-   -   1. 50 mg xylo-oligosaccharide powder was (a) left alone, or (b)         mixed with 10 mg cellobiose, (c) mixed with 10 mg MLGOs or (d)         mixed with 10 mg manno-oligosaccharides.     -   2. 0.5 mL water was added, and the tubes were incubated at room         temperature for 5 minutes until water had fully soaked into the         powder.     -   3. Each tube was then vortexed at high speed for 30 seconds.     -   4. An undissolved pellet remained in the         xylo-oligosaccharide-only tube (a), which was absent from all of         the others, whereas none of the other tubes (b-d) had pellets         remaining.

Example 3—Baked Goods with Improved Characteristics

Combinations of cellobiose (cell₂), xylo-oligosaccharides (XOS), and cellulose produce cookies with improved characteristics

-   -   1. 40 g all-purpose flour, ⅛ teaspoon baking soda, and 1/16         teaspoon salt were mixed together.     -   2. 1 oz unsalted butter, half large egg yolk, and ¼ teaspoon         vanilla extract were whisked with 20 g oligosaccharide mix         (comprising xylo-oligosaccharides and/or cell₂) and optionally 6         g cellulose polysaccharide and was added to the mixture. There         were 4 oligosaccharide mixes tested: 100% xylo-oligosaccharides,         67% xylo-oligosaccharides; 33% cell₂, 33% xylo-oligosaccharides;         67% cell₂, and 100% cell₂.     -   3. 30 g chocolate chips were mixed into the mixture.     -   4. 40 g balls were baked for 15 minutes at 350° F.

Without cellulose, the xylo-oligosaccharide-only cookies melted too quickly and formed crisp cookies that were too thin, and the cell₂-only cookies were dry and crumbly, as shown in FIG. 1. Cookies with combinations of cell₂ and xylo-oligosaccharides held their structure better and looked more like cookies. Of the cookies that contained cellulose polysaccharide, all developed cookie properties except for the cell₂-cellulose cookie, which was too crumbly. FIG. 2 shows the cookies fresh out of the oven (FIG. 2, panel a) and cut in half after a cooling period (FIG. 2, panel b). When cut, the cookies with combinations of oligosaccharide types, or oligosaccharide-polysaccharide combinations maintained their structure best. Cookies with combinations of cellobiose and xylo-oligosaccharides had better structure and mouthfeel than those made using only a single type of oligosaccharide. In conclusion, oligosaccharide combinations and oligosaccharide-polysaccharide combinations perform better as sugar substitutes in cookies than individual oligosaccharides.

Example 4—Improved Sweetness

Demonstrating improved sweetness of combinations of cello-oligosaccharide and xylo-oligosaccharide combinations

-   -   1. Five oligosaccharide solutions were created:         -   a. 40 mg/mL xylo-oligosaccharide         -   b. 80 mg/mL xylo-oligosaccharide         -   c. 120 mg/mL cellobiose         -   d. 120 mg/mL cellobiose, 40 mg/mL xylo-oligosaccharide         -   e. 120 mg/mL cellobiose, 80 mg/mL xylo-oligosaccharide     -   2. Eleven participants were asked to taste 2 mL samples of the         solutions sequentially from (a)-(e). Before each tasting,         participants washed their mouths with water and after each         tasting they were asked to assign a numerical value to the         sweetness of the solution. The first solution in which they         could taste sweetness was arbitrarily assigned a 1, and later         solutions were assigned a number based on the factor by which         they were sweeter than the former. Values were standardised to 1         for comparison.

As shown in FIG. 3, the results show a synergistic impact of sweetness in the solutions with combinations of cellobiose and xylo-oligosaccharides compared to the solutions with only cellobiose or xylo-oligosaccharides.

Example 5—Improved Solubility of Cellobiose when Combined with Xylo-Oligosaccharides

1. Solutions/suspensions of cellobiose at concentrations from 20-320 mg/mL were vortexed for 30 seconds alone (FIG. 4, panel a), in the presence of half the concentration of xylo-oligosaccharides (FIG. 4, panel b), or the same concentration of xylo-oligosaccharides (FIG. 4, panel c).

2. Dissolution was enabled more readily at higher concentrations through the presence of xylo-oligosaccharides (e.g., at 80 mg/mL).

Example 6—Modifying Hygroscopicity of Oligosaccharide Powder by Changing Compositions

The compositions are to be used in a wide range of foodstuff, cosmetic, or nutraceutical applications, therefore the required hygroscopicity for each application can vary. The aim of this example was to test if hygroscopicity can be adapted by altering the oligosaccharide compositions.

-   -   1. 5 g of oligosaccharide compositions (cellobiose, 4:1         cellobiose:xylo-oligosaccharide, 3:2         cellobiose:xylo-oligosaccharide, 2:3         cellobiose:xylo-oligosaccharide, 1:4         cellobiose:xylo-oligosaccharide, xylo-oligosaccharide) were         incubated for 10 hours at 25° C. in 100% humidity.     -   2. After incubation, oligosaccharide samples were cut using a         kitchen knife to demonstrate water capture. The cellobiose and         the 4:1 cellobiose:xylo-oligosaccharide samples effectively         resisted water uptake, whereas the other samples increasingly         absorbed water, as shown in FIG. 5. This shows that the         hygroscopicity of the composition can be modified to the desired         level in order to meet the requirements of its application.

Example 7—Baked Goods Made Using Undigested Polymeric Cellulose

Undigested polymeric cellulose from hydrolase reaction can perform functionally in cakes as well as untreated polymeric cellulose

-   -   1. 10 g microcrystalline cellulose was incubated for 36 hours at         37° C. in 400 mL solution containing 2 mg GH7 cellobiohydrolase         I (Trichoderma longibrachiatum), 5 mg GH12 cellulase         (Aspergillus niger), and 0.3 mg GH6 cellobiohydrolase II         (microbial) (all purchased from Megazyme, Ireland) with constant         agitation at 800 rpm.     -   2. After the reaction, the oligosaccharide profile was analysed         by thin-layer chromatography showing 41% breakdown of polymeric         cellulose into cello-oligosaccharides comprising mainly         cellobiose with some cellotriose, cellotetraose, and glucose         (shown in FIG. 6).     -   3. The cello-oligosaccharide mixture was separated from the         undigested cellulose through filtration and both were dried.     -   4. The undigested cellulose from the reaction was heated at         100° C. for 1 hour in 1M NaOH before being washed with water         until neutral and dried.     -   5. 2 g dried cello-oligosaccharide mixture was mixed with either         2 g dried undigested cellulose from the reaction or 2 g         microcrystalline cellulose.     -   6. The two samples were whipped with 4 g unsalted butter, before         mixing in 4 g egg, and then 4 g flour.     -   7. 4 g semi-sweet chocolate chips were added to the batter.     -   8. Mini cupcakes were baked at 37° C. for 10 minutes.     -   9. Cakes were cooled and cut in half. Results showed that the         dried undigested cellulose from cellulolytic reactions performed         identically to microcrystalline cellulose in cake structure.

Example 8—Baked Goods Made Using Undigested Polymeric Lignocellulose

Undigested polymeric lignocellulose from partial cleavage of corn cob can be added to cake mix without decrease in cake properties.

-   -   1. 10 g dried corn cob was grated into very fine pieces, ground         in a slurry using a pestle and mortar, and incubated at 100° C.         for 30 minutes.     -   2. The slurry was then incubated for 36 hours at 37° C. in 400         ml solution containing 1.6 ml T. reesei cellulase extract.     -   3. After the reaction, the oligosaccharide profile was analysed         by thin-layer chromatography showing 68% breakdown of polymeric         lignocellulose into oligosaccharide comprising mainly cellobiose         with some xylose and glucose.     -   4. The oligosaccharide mixture was separated from the undigested         lignocellulose through filtration and dried.     -   5. Three samples (4 g dried oligosaccharide mixture; 2 g dried         oligosaccharide mixture plus 2 g dried undigested         lignocellulose; and 4 g dried undigested lignocellulose) were         whipped with 4 g unsalted butter, before mixing in 4 g egg, and         then 4 g flour.     -   6. Mini cupcakes were baked at 37° C. for 10 minutes.     -   7. Cakes were cooled and cut in half. As shown in FIG. 7, the         results showed that undigested lignocellulose from cellulolytic         reactions alone gave poor structural support to the cake.         However, in combination with oligosaccharides, undigested         lignocellulose gave comparable support to cake structure.

Example 9—Baked Goods with Undigested Polymeric Lignocellulose from Partial Cleavage of Mahogany Wood, Wheat Bran, and Poplar Wood

Undigested polymeric lignocellulose from partial cleavage of mahogany wood, wheat bran, and poplar wood functions better in cakes than fresh mahogany wood, wheat bran, and poplar wood

-   -   1. 10 g dried mahogany wood, wheat bran, and poplar wood were         ground in a slurry using a pestle and mortar and incubated at         100° C. for 30 minutes.     -   2. The mahogany slurry was incubated for 36 hours at 37° C. in         400 ml solution containing 1.6 ml T. reesei cellulase extract         and 2 mg GH26 Mannanase (Cellvibrio japonicas; purchased from         Megazyme, Ireland). The wheat bran slurry was incubated for 36         hours at 37° C. in 400 mL solution containing 1.6 ml T. reesei         cellulase extract. The poplar slurry was incubated for 36 hours         at 37° C. in 400 mL solution containing 2 mg GH7         cellobiohydrolase I (Trichoderma longibrachiatum), 5 mg GH12         cellulase (Aspergillus niger), 0.3 mg GH6 cellobiohydrolase II         (microbial) (all purchased from Megazyme, Ireland), 10 mg         Aspergillus oryzae xylanase (purchased from Sigma).     -   3. After the reaction, the oligosaccharide profile was analysed         by thin-layer chromatography showing 68% breakdown of polymeric         lignocellulose into oligosaccharide comprising mainly cellobiose         with some xylose and glucose.     -   4. The oligosaccharide mixture was separated from the undigested         lignocellulose through filtration and dried.     -   5. For each of the three lignocellulose types, 2 g dried         oligosaccharide mixture was mixed with 1 g dried undigested         polysaccharide from the reaction or 1 g fresh lignocellulose.         For each of the three lignocellulose types, the two 3 g         saccharide compositions made were whipped with 3 g unsalted         butter, before mixing in 3 g egg, and then 3 g flour.     -   6. Mini cupcakes were baked at 37° C. for 10 minutes.     -   7. Cakes were cooled and analysed. As shown in FIG. 8, the         results showed that the fresh lignocellulose incorporated         less-well into the structure of the cake than the recombined         undigested lignocellulose from the enzymatic reactions did. In         the former, distinct pieces of lignocellulose were conspicuous         in the mahogany and wheat bran cakes, and less so in the poplar         cake. In contrast, lignocellulose pieces were hardly noticeable         in the cakes containing recombined undigested lignocellulose         from the enzymatic reactions.

Example 10—Gastrointestinal Tolerance

Addition of polymeric cellulose to cellobiose-xylo-oligosaccharide compositions improves gastrointestinal tolerance.

The compositions are to be used in a wide range of foodstuffs, ideally up to levels comparable to sugar consumption in the average Western diet (˜80 g/day). It is known that, at these levels, oligosaccharides, such as xylo-oligosaccharides, can cause gastrointestinal distress, including diarrhoea, discomfort, and bloating. For xylo-oligosaccharides the highest tolerated dose is 12 g/day. The aim of this example was to test if adding different polysaccharides to the oligosaccharide preparation before consumption would increase the gastrointestinal tolerance of the oligosaccharides, for example, by slowing gastric emptying, and enable far higher volumes to be comfortably consumed.

-   -   1. The experiments were performed on 2 healthy male volunteers         aged 22 and 31.     -   2. For 17 days, each volunteer consumed an average of 30 g test         oligosaccharides comprising cellobiose and xylo-oligosaccharides         at ratios from 0:1 to 4:1. The maximum consumed on a single day         was 50 g and the minimum was 20 g.     -   3. One volunteer reported diarrhea on day 2 and heavy diarrhoea         on day 17. The second volunteer reported minor discomfort and         bloating on some days.     -   4. For the next 12 days, each volunteer consumed an average of         70 g of test saccharides comprising cellobiose and         xylo-oligosaccharides at ratios from 0:1 to 4:1, supplemented         with microcrystalline cellulose or carboxymethylcellulose at         5-33% of the total test saccharide. The maximum consumed on a         single day was 110 g and the minimum was 40 g.     -   5. No gastrointestinal symptoms were observed.

This confirmed that concomitant consumption of polysaccharides with the oligosaccharides improves tolerance and enables comfortable consumption of much larger amounts of oligosaccharide and at levels comparable to sugar consumption in the average Western diet (˜80 g/day).

Example 11—Moisture Content

Four different compositions were made by mixing individual saccharide powders and undigested biomass. Sample 1 comprises 15% undigested biomass mixed with 45% xylo-oligosaccharide and 40% cellobiose w/w. Sample 2 comprises 50% xylo-oligosaccharide mixed with 50% cellobiose w/w. Sample 3 comprises 10% xylo-oligosaccharide mixed with 90% cellobiose w/w. Sample 4 comprises 90% xylo-oligosaccharide mixed with 10% cellobiose w/w.

The TES-AC-097 (UKAS) method was used to measure the moisture content. In this method the sample was heated to 70° C. in a vacuum chamber overnight and the loss in weight was measured. The moisture content results are given in Table 1 below. Sample 1 had the highest moisture content whereas sample 3 had the lowest. Samples 2 and 4 had intermediate moisture content between these two extremes and had similar moisture content to each other. The effect of moisture on flowability of particles can vary depending on the nature of the material. When particles absorb water, they can become cohesive and flow properties can be adversely affected. The higher moisture content found in Sample 1 may provide improved characteristics such as binding, moistness, etc. in baked goods.

TABLE 1 Moisture content of powders (TES-AC-097 (UKAS)) Sample number Moisture content (g/100 g) Sample 1 4.01 Sample 2 1.2 Sample 3 0.7 Sample 4 1.4

Example 12—Digi Eye Imaging

Samples from Example 11 were used and colour images were captured using a DigiEye system (Verivide). This instrument comprises an imaging cabinet with controlled D65 lighting conditions and a camera. Diffuse lighting, a fixed magnification, and consistent presentation conditions were used for all images. FIG. 9 shows colour calibrated DigiEye images for all samples. The results for the imaging show that Sample 1 has a different colour due to the presence of biomass as compared to oligosaccharide mixtures in samples 2, 3 and 4.

Example 13—Colour Analysis

Colour measurements for samples from Example 11 were taken in triplicate using a CM-5 instrument (Konica Minolta) according to method TES-CM-126. The samples were transferred into a glass petri dish and the average colour measurements were performed on a 30 mm diameter surface area in reflectance mode using a D65 illumination and 10° observation.

Colour measurements were recorded using CIELAB colour space, three coordinates (L*, a*, b*) are associated with each colour:

L*: Lightness (where L*=0 is black and L*=100 is white) is as shown in FIG. 10C.

a*: Position along an axis from green to red (where positive a* values indicate redness and negative a* values indicate greenness) is as shown in FIG. 10A.

b*: Position along an axis from blue to yellow (where positive b* values indicate yellowness and negative b* values indicate blueness) is as shown in FIG. 10B.

The four samples all had significantly different L*, a*, b* values from each other, Sample 1 being the most different as shown by the colour differences ΔE in Table 2. Sample 3 had the whitest colour, white being defined by the L*, a*, b* values 100, 0, 0, respectively. Sample 1 had the darkest colour and had the strongest red and yellow colour. Sample 1 also showed the widest confidence intervals due to the non-uniformity of the powder with some dark and light particles. The colour differences ΔE between all the samples are greater than 1, representing a visually perceptible colour difference. In summary, the colour of Sample 1 was the most different from the other samples and Sample 3 was the closest to a white colour.

TABLE 2 Table of the colour differences ΔE between samples Sample 1 Sample 2 Sample 3 Sample 4 White Sample 1 — 20.13 22.77 17.34 27.28 Sample 2 20.13 — 2.99 3.25 7.30 Sample 3 22.77 2.99 — 6.23 5.00 Sample 4 17.34 3.25 6.23 — 10.24 White 27.28 7.30 5.00 10.24 —

Example 14—Hygroscopicity Measurements

Approximately 5 g of each sample from Example 11 was weighed into aluminium foil dishes and covered with foil. Several holes were made in the foil cover to allow moisture to enter the dish but prevent contamination from airborne debris or powder being lost. The samples were stored in a temperature and humidity-controlled room (20° C. and 70% relative humidity) and the change in weight of the samples measured after 24 and 48 hours. Each sample was measured in duplicate. The results of the hygroscopicity measurements as shown in FIG. 11 show that all samples had the tendency to pick up moisture from the atmosphere at 20° C. and 70% relative humidity. Sample 3 had the lowest moisture content to begin with and picked up less moisture than the other samples. The trend on graph for sample 3 suggests that moisture pickup had reached an equilibrium or was very close to an equilibrium with the surrounding atmosphere. This sample had not clumped together after 48 hours. Sample 1 had the highest moisture content and absorbed moisture at a faster rate than sample 3 which is unexpected. The rate of moisture pick-up of sample 1 was similar to samples 2 and 4. After 48 hours, sample 1 had formed some clumps. Samples 2 and 4 had intermediate moisture content between samples 1 and 3 and absorbed moisture from the atmosphere at a similar rate to each other up to 24 hours. Sample 4 absorbed more moisture between 24 and 48 hours compared with sample 2. Sample 3 did not show any clump formation but sample 4 had lost its particulate nature and formed a viscous liquid. It could therefore be described as deliquescent.

The hygroscopicity measurements were repeated on samples that had been dried overnight at 70° C. under vacuum. This was to ensure that any historical moisture absorbed by the samples was removed and were dry when the hygroscopicity test was started. It was noteworthy to report that after drying sample 1 was in the form of hard lumps of various sizes and difficult to break. The lumps were broken up and the powder sieved through a 500 μm sieve to obtain free flowing particles of the sample. Samples 2-4 were free-flowing powders after drying. The percentage moisture gained is given in FIG. 6 and as before sample 3 absorbed the least amount of moisture from the atmosphere over the 96-hour period. Sample 4 absorbed the highest amount of moisture in the same period and had changed to a viscous liquid as was found in the first study. The rate of moisture pickup by sample 4 was greater than the other three samples. Sample 1 absorbed more moisture than sample 2, but the rate of moisture pickup appeared to be similar for these two samples

Example 15—Cohesion Strength of Powders

The cohesion strength describes a powder's internal flow resistance, which depends on the adhesive forces between the particles. The measurements for samples made in Example 11 were conducted with an Anton Paar MCR Rheometer MCR102 equipped with a Powder Cell, a powder fluidizer with mass-flow controller (Fluidization Set Scientific), and a two-blade stirrer. The cohesion strength is determined with the two-blade stirrer from the torque recorded during the measurement and a geometry-specific factor. The method consists of two steps. During the first interval, residual influences from previous powder handling are erased. This is known as the Pressure-Drop Method. This was achieved by fully fluidizing the sample for 60 seconds. During the second interval, a constant rotational speed of 8 rpm was set while the volumetric flow was zero. The cohesion strength S in Pa was calculated by using linear regression over the last 20 data points.

The examples of the traces of the cohesion strength obtained of samples 2 to 4 are shown in FIG. 12. The analysis of the traces is given in Table 3. The cohesion strength of samples 2 and 3 was significantly lower than that of sample 4. The higher value of sample 4 indicate higher cohesive forces between the particles. This might be due to different particle sizes and particle-size distributions and thus, different cohesion strengths. Sample 4 also had higher bulk density, suggesting greater inter-particle interaction and this may also be a factor contributing to the higher cohesion strength. Sample 1 was not measured as it could not be fluidised. This suggests that the cohesion strength of this powder was high, and this may be due to the high moisture content of this sample as well as other factors.

TABLE 3 Cohesion strength of powder samples. Sample number Cohesion Strength (Pa) Sample 1 Did not fluidise Sample 2 207.1 ± 4.6 Sample 3 217.5 ± 2.6 Sample 4 380.5 ± 7.6

Example 16—Viscosity

For viscosity measurements, 2 solutions were made comprising a 1:2 and a 2:1 ratio of cellobiose and xylo-oligosaccharides. The samples were tested using a Brookfield HDB VE roto-viscometer using standard testing procedures, a 400 mL sample is taken in a tall-form beaker to ensure that no container effects occur. The instrument is operated as per the manufacturer's instructions with respect to ranges. Rotoviscometry using spindle code 61, spindle speed 100 rpm, and at 22° C. (see FIG. 13).

Example 17—Cream Cheese Icing Made Using Oligosaccharide Mixtures

7 g butter and 21 g cream cheese were combined. 50 g icing sugar or premade Cell₂/XOS mixture were mixed in. Results are shown in FIG. 14.

When Cell₂ is used alone the structure of the icing is very dry and crumbly and as a result it is unable to hold a proper structure of icing and function as icing properly. As Cell₂ is replaced by XOS in 10% increments the structure becomes increasingly better able to stick together. Between about 50:50 and about 20:80 Cell₂:XOS w/w ratios the texture of the icing compositions is similar to that when using sugar and has a sturdy thick cream cheese icing consistency. Between about 50:50 and about 20:80 Cell₂:XOS w/w ratios the surface appearance of the icing compositions is similar to that when using sugar and has a smooth, shiny surface that retains structure like it does when sugar is used. As the mixture approaches and reaches 100% XOS the texture becomes increasingly thick and lumpy and/or crystallised as the XOS fails to incorporate properly into the icing, and the surface is unable to hold the whipped appearance of icing. Acceptable Cell₂:XOS w/w ratio ranges for cream cheese icing include 50:50 to 20:80 with optimal being 30:70.

Example 18—Meringue Made Using Oligosaccharide Mixtures

The product was made as follows:

1. Whisk 30 g egg whites until foamy.

2. Add 30 g sugar or premade Cell₂/XOS mixture half at a time.

3. Whisk to stiff peaks.

Results are shown in FIG. 15. When Cell₂ is used alone the structure of the meringue is dry, dull and brittle and as a result it is unable to hold a proper structure of meringue and function as meringue properly. As Cell₂ is replaced by XOS in 10% increments the structure becomes increasingly better able to stick together. Between about 70:30 and about 10:90 Cell₂:XOS w/w ratios the texture of the meringue composition is similar to that when using sugar and has a sturdy thick meringue consistency. Between about 70:30 and about 10:90 Cell₂:XOS w/w ratios the surface appearance of the meringue compositions is similar to that when using sugar and has a smooth, shiny surface that retains structure like it does when sugar is used. As the mixture approaches and reaches 100% XOS the texture becomes increasingly thin and the surface becomes shinier. Acceptable Cell₂:XOS w/w ratio ranges for meringue include 70:30 to 10:90 with optimal being 30:70

Example 19: Chocolate Chip Muffin/Cupcakes Made Using Oligosaccharide Mixtures

The products were made as follows:

1. Combine 64 g flour, ¾ tsp baking powder, ⅛ tsp salt, and 25 g sugar or premade Cell2/XOS mixture.

2. Separately combine 45 g milk, 17 g sunflower oil, and 13 g egg.

3. Mix the wet ingredients into the dry.

4. Fold in 30 g chocolate chips.

5. Weigh out 55 g batter per muffin.

6. Bake 12 minutes in a preheated oven at 170° C.

Results are shown in FIG. 16. When Cell₂ is used alone the structure of the muffin is dry, dense, lumpy and readily crumbles and as a result it is unable to hold a proper structure of muffin and function as muffin properly. The surface browns unevenly and wrinkles far more and is far lumpier than with sugar. As Cell₂ is replaced by XOS in 10% increments the structure becomes increasingly better able to stick together. Between about 90:10 and about 10:90 Cell₂:XOS w/w ratios the texture of the muffin compositions is similar to that when using sugar and has a soft, cakey, chewy consistency, is able to hold moisture better and has a more sugar-like rise and colour. Between about 90:10 and about 10:90 Cell₂:XOS w/w ratios the surface appearance of the muffin compositions is similar to that when using sugar: it browns more evenly and has a more cake-like wrinkling structure.

As the mixture approaches and reaches 100% XOS the texture becomes increasingly thick and dense, and the surface becomes excessively brown and does not display the typical wrinkled/cracked structure of a muffin surface, instead forming a solid film-like surface. Acceptable Cell₂:XOS w/w ratio ranges for muffins/cupcakes include 90:10 to 10:90 with optimal being between 60:40 and 40:60.

Example 20: Peanut Butter Cookies Made Using Oligosaccharide Mixtures

The products were made as follows:

1. Cream 14 g butter and 23 g sugar or premade Cell2/XOS mixture.

2. Add 7 g egg and 0.7 g vanilla extract and combine thoroughly.

3. Add 15 g peanut butter and mix until combined.

4. Mix in 20 g flour, 0.35 g baking powder, and 0.35 g baking soda.

5. Weigh out 20 g of dough, roll into a ball.

6. Bake 9 minutes in a preheated oven at 160° C.

Results are shown in FIG. 17. When Cell₂ is used alone the structure of the cookie is very dry and dense as Cell₂ does not incorporate well into the dough. As a result the composition is unable to hold a proper structure of a cookie. When Cell₂ is used alone the surface is also too light-colored and does not brown enough. As Cell₂ is replaced by XOS in 10% increments the structure becomes increasingly better able to stick together. Between about 30:70 and about 10:90 Cell₂:XOS w/w ratios the texture of the cookie compositions is similar to that when using sugar and has a chewy, crumbly consistency. Between about 30:70 and about 10:90 Cell₂:XOS w/w ratios the surface appearance of the cookie compositions is similar to that when using sugar and has a cracked, wrinkled, evenly-browned surface that retains structure like it does when sugar is used. As the mixture approaches and reaches 100% XOS the surface becomes too dark and pitted, the shape is unevenly distributed and partly burns at the edges, and the texture becomes increasingly thick, lumpy and granular as the XOS fails to incorporate properly into the cookie and sometimes forms clumps that will not readily break apart. Acceptable Cell₂:XOS w/w ratio ranges for cookies include about 30:70 to about 10:90 with optimal being between about 20:80 and about 10:90.

Example 21: Jams Made Using Oligosaccharide Mixtures

Products were made as follows:

1. Combine 60 g raspberries and 30 g sugar or premade Cell₂/XOS mixtures in a small sauce pan.

2. Cook over medium low heat until it reaches thread stage.

Results are shown in FIG. 18. When Cell₂ is used alone the structure of the jam is dry, sandy, dull, dense and solid and so unable to hold a proper structure of jam and function as jam properly.

As Cell₂ is replaced by XOS in 10% increments the structure becomes increasingly better able to stick together and hold moisture. Between about 50:50 and about 10:90 Cell₂:XOS w/w ratios the texture of the jam compositions is similar to that when using sugar and has a moist, smooth, and soft consistency that easily flows and can be spread. Between about 50:50 and about 10:90 Cell₂:XOS w/w ratios the surface appearance of the jam compositions is similar to that when using sugar and has a smooth, shiny surface like it does when sugar is used. As the mixture approaches and reaches 100% XOS the texture becomes increasingly thin and translucent and the XOS can fail to incorporate properly into the jam and sometimes forms clumps that will not readily break apart. Acceptable Cell₂:XOS w/w ratio ranges for jam icing include about 50:50 to about 10:90 with optimal being about 30:70 to about 10:90.

Example 22: Ice Cream Made Using Oligosaccharide Mixtures

A recipe that can be used to make such products is as follows:

1. Place ice cream maker insert into the freezer at least one day ahead of making ice cream.

2. Heat 284 g double cream, 300 g full fat milk, and 57.5 g sugar or premade Cell₂/XOS mixture in a medium sauce pan until just steamy.

3. Whisk together 60 g egg yolks and 57.5 g sugar or premade Cell2/XOS mixture until lightened in colour.

4. Pour about ⅓ of the steamy cream mixture into the egg mixture. Combine and pour back into the sauce pan.

5. Cook, stirring constantly until the mixture thickens enough to coat the back of a spoon.

6. Chill custard overnight.

7. Pour custard into ice cream machine and churn for 10-30 minutes.

8. Scoop into a container and freeze at least 3 hours before serving.

100% Cell₂ is expected to be too dull, thick and grainy and 100% XOS is expected to be shiny, lumpy with crystallised XOS and too liquid. A combination of the two would be expected to hold well, be smooth, and have the proper amount of shine.

Example 23: Chocolate Made Using Oligosaccharide Mixtures

A recipe that can be used to make such products is as follows:

1. Combine 700 g cocoa mass, 50 g cocoa butter and 250 g sugar or premade Cell₂/XOS mixture with mild heat until sugar or premade Cell₂/XOS mixture melts and everything is well combined.

2. Temper the chocolate and use as needed.

100% Cell₂ is expected to be dry, crumbly, and dull. 100% XOS is expected to be runny, shiny, and crystallised/lumpy. A combination of the two is expected to result in shiny chocolate with the proper density and texture.

Example 24: Pate De Fruits Made Using Oligosaccharide Mixtures

A recipe that can be used to make such products is as follows:

1. Bring 500 g fruit puree to boil.

2. Combine 100 g sugar or premade Cell₂/XOS mixture with 12.5 g pectin powder.

3. Add the dry mix to the puree and bring to boil whisking continually.

4. Add 200 g sugar or premade Cell₂/XOS mixture and bring to softball stage (112° C.−116° C.).

5. Remove from heat and add 5 g lemon juice.

6. Pour into paper lined mould.

7. Allow to set before removing from the pan.

8. Cut into pieces.

100% Cell₂ is expected to be dull, dry, opaque, and crumbly. 100% XOS is not expected to set properly and will be shiny and translucent (neither will reach temperatures). A combination of the two is expected to result in a pate de fruits that is soft, chewy/sticky, and slight translucent.

Example 25: Soft Caramels Made Using Oligosaccharide Mixtures

A recipe that can be used to make such products is as follows:

1. In a sauce pan cook 250 g sugar or premade Cell₂/XOS mixture, 250 g double cream, and 125 g glucose to 112° C.

2. Remove from heat and add 65 g soft butter.

3. Cook further to firm ball stage (118-120° C.).

4. Pour into a paper lined fudge tray and allow to cool.

5. Once cold cut into bite sized pieces.

100% Cell₂ is expected to be dry, dull, and crumbly. 100% XOS is not expected to set properly and will be shiny and crystallised/lumpy (neither will reach temperatures). A combination of the two should result in a soft chewy caramel that is slightly shiny.

Example 26: Marshmallows Made Using Oligosaccharide Mixtures

A recipe that can be used to make such products is as follows:

1. Bloom 25 g gelatine in 180 g of water in a bowl of a mixer.

2. Once the gelatine is bloomed, heat the over a bain-marie to dissolve the gelatin.

3. Heat 180 g of water, 300 g sugar or premade Cell₂/XOS mixture, and 150 g glucose to 116° C., remove and stir in the remaining 60 g of glucose.

4. Pour the syrup into the gelatine mixture and whisk till cooled and thickened. Transfer to a piping bag.

5. Sieve 500 g icing sugar and 500 g corn flour together and divide onto trays.

6. Pipe marshmallow mix onto icing sugar mixture.

7. Allow to set.

8. Cut into bite sized pieces and dust-off excess sugar.

100% Cell₂ is expected to be dry, dull, and crumbly. 100% XOS is expected to be shiny but will not set (neither will reach temperatures). A combination of the two may result in a properly set marshmallow that has the correct aeration and chewy texture.
